SAMUEL K. DENNIS, OF CHICAGO, ILLINOIS, ASSIGNOR TO INTERNATIONALHARVESTEE COMPANY, A CORPORATION OF NEW JERSEY.

HAY-LOADER.

To all whom it may concern:

Be it known that I, SAMUEL K. DENNIS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hay-Loaders, of whichthe following is a specification.

My invention relates to hay loaders, and in particular to theconstruction of the draft devices whereby the loader is connected with aWagon; its object being to provide a mechanism that may be convenientlymanipulated in a manner to vary the height of the tongue connection andits operative length. These objects are attained by means of themechanism illustrated in the accon'ipanying drawings, in which Figure 1is aside elevation of a hay loader embodying my invention; Fig. 2 is atop view of the draft devices; Fig. 3 is a side elevation, partly insection, of Fig. 2; Fig. i is an enlarged cross section on line i i-B ofFig. 3; Fig. 5 is an enlarged cross section along line BC of Fig. 3;Fig. 6 is a side elevation of part of the tongue adjusting mechanism;Fig. 7 is a vertical section of part of the tongue adjusting mechanismalong line CD of Fig. 2; F 8 is a verti cal section of Fig. 7 along lineDE; Fig. 9 is a vertical section of one of the tongue controllingmembers.

The same reference characters designate like parts throughout theseveral views.

1 represents carrying wheels mounted upon an axle 2 having a rakingcylinder 3 in rear thereof and adapted to swing about the axis of theaxle, and 4 represents an elevator designed to convey the hay upwardtoward a wagon to which the loader may be attached.

5 represents a draft frame including a transverse bar 6, and secured tothe elevator frame members are longitudinally arranged fixed tonguemembers 7 spaced apart and adapted to loosely receive a tongue member 8between them, brace members 9, having their rear ends secured toopposite ends of said transverse bar and their forward ends to the frontends of the fixed tongue members; brace members 10 having their lowerends secured to the transverse bar and inclining upward are secured attheir upper ends to the elevator frame and brace members 11, havingtheir lower ends secured to Specification of Letters Patent.

the front ends of the fixed tongue members and their upper ends to theside members of the elevator frame.

Secured to the front end of the loose tongue member is a hook 12,whereby it may be attached to a wagon, and 13 represents plates securedto the upper and lower sides of the loose tongue member and having aseries of holes 11 therein that extend through the tongue.

15 represents a yoke received between the forward ends of the fixedtongue members and adapted to receive the loose tongue member in aslid-able manner, the yoke having lateral openings 16 in its side wallsthat are adapted to receive bolts 17 that extend through openings in thefixed tongue members andreceive at their outer ends the brace members 9and 11 and nuts 18, the bolts being free to turn with the yoke. The yokeis provided with vertical openings 19 adapted to receive a pin 20 thatmay pass through any of the openings in the loose tongue for the purposeof varying the effective length relative to the fixed tongue members,and 21 represents depending ears upon opposite sides thereof at itslower end, having transverse openings therein adapted to receive a pin22 that connects them with the upper ends of the bars 28 forming part ofa swinging leg 2% adapted to sustain the weight of the forward end ofthe loader, as is common in this class of machines.

25 represents a stirrup having the form of a segment concentric with theaxis of the yoke 15 and secured to the fixed tongue member and adaptedto receive between its opposite side members the loose tongue member.

26 represents a yoke surrounding the loose tongue and having side wallscurved in a manner to be received between. the guide ribs 27 upon theinner sides of the walls of the stirrup in a slidable manner.

28 represents depending ears forming parts of the stirrup, in which isjournaled the lower transversely bent end 29 of a lever having avertically arranged hand portion 30. Secured to the bent portion of thelever, between the cars 28, is a sleeve 31, having arms 32 that havetheir outer ends pivotally connected with the lower end of the yoke 26by means of a link 33. The lever is provided with a common form ofsliding detent 34: that engages with an enlarged sector 35 in a mannerto secure it in any desired position of adjustment.

In operating the mechanism the loader is supported by means of the leg24:. The loose tongue may then be connected with the wagon, the pin 20being inserted in one of the series of openings therein for the purposeof properly adjusting the length of the draft connection to meet therequirel'nents of the position of the wagon relative to the loader, andthe hand lever 30 may then be manipulated in a manner to adjust theheight of the delivery end of the elevator from the wagon.

lVhat I claim as being my invention, and desire to secure by LettersPatent, is:

1. A draft connection for hay loaders in cluding, in combination, fixedtongue members, a loose tongue member adjustable longitudinally relativeto said fixed members and having a transverse pivotal connection withsaid fixed members, and lever mechanism operatively connecting saidtongue members in a manner whereby said loose member may be rocked andsecured in any desired position relative to said fixed members.

2. A draft connection for hay loaders including, in con'ibination, fixedtongue members, a loose tongue member adjustable longitudinally relativeto said fixed members and having a transverse pivotal connection withsaid fixed members, and a lever mechanism mounted upon the fixed membersand operatively connected with said loose member whereby the latter maybe rocked about its pivotal connection and secured in any desiredposition of adjustment.

8. A draft connection for hay loaders including, in combination, fixedtongue members having an intervening space between them, a loose tonguemember received by said space and adapted to be adjusted longitudinallythereof and having a pivotal connection with the forward ends of saidfixed tongue members, and a lever mechanism pivotally connecting therear end of said loose tongue member with said fixed members in a mannerwhereby said loose member may be rocked about its pivotal connection andsecured in any desired position of adjustment.
